SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 391,104, dated October 16, 1888.

Application filed August 20, 1888. Serial No. 283,248. 1N0 model.)

To ctZZ whom it may concern:

Be it known that I, HENRY A. WILLIAM- SON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Sash- Holders, of which the following is a specification.

My invention has relation to window-sash holders of the form which are secured either to one of the rails or stiles of the sash or affixed to the sash or casing-frame therefor, so as to frictionally engage either with the back lining of the casing or with the edge of the sash, re spectively, for holding the sash in its raised position; and it has for its object a simple, effective, and durable holder which can be applied either to the sash rail or stile, or concealed within or otherwise affixed to frame or casing therefor.

My invention accordingly consists of the combination, construction, and arrangements of parts, as hereinafter described in the specification and pointed out in the claims, reference being had to the accompanying drawings, wherein- V Figure 1 is a plan of my improved sashholder; and Fig. 2 is an elevation ofa car window or sash and frame-work therefor, the latter being partly in section,showing the application of my improved holder to the frame or to a stile of the sash.

A A represent two parallel levers having cam-shaped diverging short arms a,long arms a, and pivot holes or pins a adjacent to said short ends a.

B represents a bent plate or other spring, which is secured in position between the long arms a of levers A A by blocks 1) I), shaped to conform to the bend b of the spring, and between which the bend b preferably passes, so that it cannot readily work loose therefrom. The ends I) b of the spring B bear against the long arms a of levers A A, and have an outward action in the direction of arrows xx, Fig. 2, to cause the small arms a of thelevers A A to approach each other.

0 represents a sliding plate, the outer side, 0, of which contacts with the casing for the sash or with the edge of the sash-stile, accordingly as the holder is located. The ends 0 of the side a or plate 0 are directed rearwardly toward the levers A A, to prevent said ends catching or engaging with either the frame or sash as it is raised or lowered. The plate 0 has projecting from its rear side a slotted lug, c", in which fits a guidepin, 0*, to keep the plate in position in front of the short arms a of levers A A, against which arms said plate abuts. The pin 0 and blocks [2 b, as well as the pivots or supports of levers A A, are suitably secured to either the sash or its casing,or to a separate base-plate, as indicated at D, Fig. 1. The holder may be secured to the casing E, either on its outside or within the same, as illustrated to the right of Fig. 1, or it may be secured to one of the stiles or rails of the sash, as shown to the left of said figure. In the one case the plate 0 contacts with the adjacent edge of the sash-stile,-and in the other it contacts either with the casing-bead or back lining of the casing. The holder is so located in relation to the sash-*the contacting edge of the sash or casing against which the plate C bearsthat the spring B will exert suffioient force, through the instrumentality of levers A A, to cause the plate 0 to bear or bind against said contact edge with force enough to merely hold the sash in any position to which it may be raised or lowered, and yet not offer any undue resistance to its being raised or lowered. As the contact-surfaces ofthe plate 0 and the fixture against which it bears wear, the outward tendency of the spring B causes the small arms a a of the levers A A to approach each other, whereupon their cam-shaped ends slide the plate 0 forward to take up such wear as it occurs, such described movement being indicated by the dotted lines shown in Fig. 2.

It is evident that as the short arms a a of the levers A A bear against plate C, and the long arms 0. a are in contact with the spring B, or as the force or power of the spring is multiplied by the levers A A, a spring of small power may be used to firmly hold quite heavy sashes in their adjusted position, and, further, to economize in the cost of the holder and provide for more readily and easily putting its parts together and adjusting them in position upon a sash or casing.

My invention is applicable to all kinds of windows, whether in buildings, cars, or other structures.

I have described that I prefer to have the plate 0 bear against the sash or frame with sufficient pressure to firmly hold the sash in position when raised, and yet not interfere with raising or lowering the sashthat is to say, the sash is lowered or raised against the pressure offered by plate 0. If desired, however, before the sash is raised or lowered, manual pressure may be applied to the long arms a a of the levers to spread their short arms a a apart or move them away from the plate 0, so that it is free from the force or pressure of the spring B while the sash is being adjusted. This described movement of the levers A A can readily be made when the holder is exposed, and when concealed within the casing a suitably-located knob may be used for such described movement of the levers.

\Vhat I claim is 1. A sash-holder composed of a base-plate, two parallel pivoted levers having short camshaped arms a a, sliding plate 0, adjustably connected to said baseplate and bearing against arms a a, and spring B, acting upon the long arms of the levers, substantially as set forth.

2. A sash-holder composed of two parallel pivoted levers having sho'rt arms a. a and long arms a a, sliding plate 0, having slotted lug 0 and guide 0*, and spring B, acting upon said long arms a a, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY A. WILLIAMSON.
